A new version of RICardo (RICardo_2022)

As announced in a previous post, a new version of RICardo is now available. RICardo_2022 includes three major improvements as compared with RICardo_2017.

1. Updated trade dataset

The complete RICardo database gathers all data collected since the beginning of the project. It amounts to more than 630,000 bilateral flows in RICardo_2022 (vs. 400,000 in RICardo_2017).

The deduplicated RICardo file is an extraction of the complete data set that eliminates duplicates and zero values and favors primary sources. It gathers about 540,000 trade flows (vs. 360,000 in RICardo_2017).

The sources of this selective dataset can be visualized in the Metadata view.


2. New political dimension of trade data

About 2,000 trading entities are identified in RICardo. In the new version of RICardo, the RICentities are labelled by using the GeoPolHist dataset that lists the geopolitical entities of the world since 1816.

This adds a political dimension to the RICardo trade database by linking each RIC geopolitical entity to the growth of its political status.



3. New ‘partner’ view

The ‘partner view’ has been created to exploit the potential of the trade database in the reconstitution of trade series. It provides a view of a partner’s bilateral trade by using bilateral trade data of the reporting entities.

For example, in the current version of the database, no data is available for the reporting ‘Argentina (La Plata)’ over the period 1837-1864. Missing data can be estimated thanks to the partner view.


This is not the end of the road and there is still room for improvement. First, regarding the degree of completeness of the database. A sample of trade archives recently found is still to be added in the database (the Zenodo citation will be updated once these data are integrated). Furthermore, new sources can be found and new ways of exploiting the current database are considered. In fact, bilateral trade data can be estimated by aggregating trade data of RICentities of the type ‘city_part of’. For example, Spain’s bilateral imports and exports in the 1830s could be estimated by adding up bilateral imports and exports values of Bilbao, Cadix, San Sebastian, and Valencia (data provided by the Annales du commerce extérieur). Besides, as suggested by the new ‘partner view’ on the website, an entity’s bilateral trade can be partly reconstituted thanks to trade declarations of its reportings. Second, to keep on improving data visualization, we are thinking of the creation of new views on the website. For example, the creation of a view that would reconstitute bilateral trade time series of customs unions, such as the European Union, or Australia, Canada, South Africa before political unification.


We hope that this new material will help to fuel various and innovative research in political and trade history, and will welcome any comment that could help to further improve this open research tool.
